IMPROVEMENT IN MACHINES TO UNITE SOLES T 0 UPPERS.

Specification forming part of Letters Patent No. 216,299, dated June 10,1879; application filed April 10, 1879. c

To all whom itmay concern:

Be it known that I, ANDREW J. WILBUR, of Raynham, county of Bristol,State of Massachusetts, have invented an Improvement in Machines toUnite Soles to Uppers, of which the following description, in connectionwith the accompanying drawings, is a specification.

This invention relates to an improvementin machines to unite soles touppers in the manufacture of boots and shoes.

My invention consists in a horn to enter the.

duty of partially rotating or reversing the po-.

sition of the horn by hand when the sole and upper are being united atthe toe of the boot or shoe, and is enabled to then hold the boot orshoe with both hands, while with his foot or otherwise the horn ispartially rotated within the boot or shoe, and it becomes unnecessary tostop the machine or run it slower when working about the toe. Figure 1represents, in side elevation, a sufficient portion of a nailing orother machine having a rotary born to enter or support the materialbeing operated upon; Fig. 2, a top view thereof; Fig. 3, a sectionaldetail, and Fig. 4, a modification.

As my invention relates solely to the horn and mechanism to rotate it, Ihave not considered it necessary to show the parts of the machine forinserting the fastening material for the soles and uppers. Said partsmay be as in any well-known machine. The standard a of the machine haspivoted or loosely mounted upon it the horn 1), arranged to be turnedabout an axis substantially coincident with the axi'sof the driver orother device which introduces the sole-fastening being used.

In the form in which my invention is illustrated in Figs. 1 to 3 Iprovide apivoted arm, 0, in which is placed a slide-bar, d, having atits outer end a segment-gear, c. This slidebar has two pins, 2 3. Thepin2 is connected with a spring, f, the opposite end of which is joinedwith pin 4 on the arm 0, and the spring acts to throw the slide forwardeach time that it reaches the position shown in Fig. 2 in full lines, soas to place the teeth of the segment in position to engage the teeth ofthe pinion 71 at or near the base of and partially rotate the horn I)when the arm and segment are moved in the direction of the arrow, Fig.2, through the action of the treadle or lever '13 connected with the arm0 through the elbowlever and links j is Z. When the lever i is releasedthe spring on throws the arm and segment in the direction opposite thesaid arrow.

Below the arm '0 I have shown a plate, at, provided at one end with aprojection, 6, and at its other end with an incline, p.

Pivoted to the arm 0 is a hook or latch, a", operated upon by spring 8,so that when the slide d is pressed back within the arm 0, as it is bythe action of pin 3 upon the cam-projection 6, the slide is heldretracted by the hook 1' entering the notch 8 in the slide. This permitsthe arm and segment to be moved from its dotted to its full lineposition without coming in contact with the pinion h; but as the arm andslide reach the full-line position in Fig. 2 the end 10 of the hook '1"will be depressed by the incline 19, thereby disengaging the hook fromthe notch 8, permitting the spring f to throw the slide 0 outward intothe position shown in Fig. 3, wherein the segment is shown as engagingthe pinion h.

In Fig. 4 I have shown the pinion on the horn made as a bevel-pinion,and have placed in connection with it a beveled segment or gear adaptedto partially rotate the horn in one and then in the opposite direction,as required, but without being disengaged, the one from the other, as inFig.2, In the said ure 1 have omitted the foot-lever and its connectionswith the segment.

It will be obvious to a skilled mechanic that various forms of gear ordevices may be used between the horn and the foot or other levercontrolled by the operator, and moved when it is desired to partiallyturn the horn at the time described, and therefore I do not desire orintend to limit my invention to the exact devices shown forautomatically rotating the horn.

1 am aware in many machines for boot and shoe work, as in burnishing andpegging machines, that the last upon which the shoe was jacked andsecured has been rotated positively by mechanism consisting ofgear-wheels, 850.

I claim-- The combination, With the horn, of mechanism under control ofthe operator to positively ,ANDREW J. WILBUR.
